Abstract

We have conducted an in-situ upconversion (UC) mechanism study through fluorescence enhancement induced by electric field in the Er³⁺ doped 0.75Pb(Mg_1/3Nb_2/3)O₃-0.25PbTiO₃ transparent ceramic. Under the excitation of a 980 nm diode laser, the sample shows a strong green UC fluorescence, which increases with electric field. A maximum enhancement of 150% was achieved in fluorescence intensity by the applied electric field due the lowering of crystal symmetry by the electric field induced strains. Combined with an in-situ analysis of time-resolved spectra, we proved that the dominant UC mechanism in this system should be the energy transfer (ET) process.
